Leonid, 4Z7LES, bought some Toko
coils from ebay, quite cheap, in 100 off lots. These are the type with the larger
cores (not the recommended 10K type by G3XJP for STAR) and it is interesting
to see results that he has achieved. These coils do not have the segmented winding
area but a single winding area on what appears to be a ferrite core. This
is experimental at this time.
